// /0 33 as w O O O METHOD OF CONSTRUCTING A WINDOW ACCESSORY BACKGROUND OF THE INVENTION The present invention relates to a method of constructing a window accessory and, more particularly, to a method of attaching a window accessory to the side wall of the building while assembling it at the same angles. Such a bar assembly includes a window railing,

a window lattice or the like.

THE PRIOR ART In the prior art, such a window accessory has been assembled by welding or rivetting. Usually, the window accessory is completely assembled by skilled workmen at a remote shop and then transported to the attaching site, becausethere is need for providing some peculiar machines or apparatuses unadapted to carry about in order to accomplish all of the welding or rivetting operations. Such a finished window accessory is, however, so bulky that there is need for a large amount of storage space and packing material. It cannot be packed up so efficiently. In addition, it is almost impossible or very difficult to transport the finished window accessory from the assembling shop to the remote attaching site unless a plurality of workers cooperate each other, since the finished accessory as a whole is considerably heavy and bulky. For the same reason, it is impossible or very difficult for a single worker to lift up the completed accessory to the height of the window and then to attach it to the required side wall of the building.

Thus, most prior art window accessory which require some unhandy machines and a plurality of skillful workers are considerably expensive and cannot be widely used, because an abundant supply of cheap labour cannot be almost expected.

Recently, in order to said disadvantages due to shopassembling, a knockdown window accessory that may be assembled at the attaching site by means of setscrews or the like has been proposed. But, in effect, such a knockdown accessory is completely assembled on the ground, and then the completed accessory is lifted up to the required height by plurality of workers. Consequently, there still remains disadvantages resulting from handling a bulky finished window accessory of great weight with cooperation of more than two workers.

OBJECT OF THE INVENTION An important object of the present invention is to provide a method for constructing a window accessory in which the window accessory will be attached to the side of the building while being assembled at the same place.

Another object of this invention is to provide a method of a window accessory whereby the window accessory can be constructed by a single unskilled worker at relatively low cost.

SUMMARY OF THE INVENTION In accordance with the present invention, there is provided a method of constructing a window accessory in which one of the two horizontal bars is first fixed to the side of the building, at least one vertical bar is next fixed to said horizontal bar, the other horizontal bar is then fixed to said vertical bar, and the other horizontal bar is last fixed to side of the building.

Numerous other objects and advantages of the present invention will become readily apparent from the following detailed description taken in conjunction with the accompanying drawings which show the preferred embodiment.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 to 4 show each step of the first embodiment of the present invention, in which A is a front view of a window railing and B is a side view of it; and

FIG. 5 to 8 show each step of the second embodiment of this invention, in which A is a front view of a window lattice and B is a side view of it.

DETAILED DESCRIPTION OF THE INVENTION In the preferred embodiment shown in FIG. 1, 2, 3 and 4, the window accessory is a window railing of which components will be readily interconnected by simple securing means such as a setscrew.

The main components of this window railing are an upper horizontal bar 10, a lower horizontal bar 20 and nine vertical bars 30. The upper horizontal bar 10 consists of a body member 10a of a square pipe and an arm member'lOb of a U-shaped plate. The body member 10a is provided with a series of nine tapped holes 11 on the front wall at equal spaces, which the tapped holes 1 I serve as connections with the L-shaped vertical bars 30. Alternatively, said tapped holes as connections 11 may be provided on any wall other than the front wall, that is to say, on the top wall, the bottom wall or the rear wall. Said U-shaped arm member 10b has a front leg 12 and a rear leg 13 which are parallel to each other. The front leg 12 is fixed to the rear wall of the body member 10a by means of setscrews 14. On the other hand, the rear leg 13 will be fixed to the side wall of the building H by means of setscrews 15, that is to say, this rear leg 13 will serve as connection with the building H. Said screw connections 11 with the vertical bars 30 are, therefore, completely separated from this screw connection 13 with the building H. The arm member 10b is usually attached to both ends of the body member 10a. If there is a door receptacle at one sidel of the window, said U-shaped arm member 10b will be removed from the side concerned to enable slide doors to pass by. In that case, said end of the body member 10a will be fixed to the side wall of the door receptacle by another attaching member which cannot prevent the slide door from passing through there. The L-shaped vertical bars of channel steel have a vertical member 300 and a horizontal member 30b. The vertical member 30a isprovided with a hole 31 on the upper end, which will serve as connection with the body member 10a of the upper horizontal bar. The rear end of the horizontal member 30b is provided with a hole 32 which will serve as connection with the lower horizontal bar 20. The lower horizontal bar 20 of a angle bar has a horizontal member 20a and a vertical member 20b. This horizontal member 20a is provided with a series of nine tapped holes 21 at the same spaces as said tapped holes 11 on the body member 10a. These tapped holes 21 will serve as connections with the horizontal members 30b of the L-shaped vertical bars 30. Said vertical member 20b is provided with seven holes 22 which will serve as connections with the building H.

Thus, these connections 22 with the building H are separated from said connections 21 with the vertical bars 30. As a result of the above arrangement, fixing of the vertical bar 30 to the lower horizontal bar 20 will not hinder fixing of the lower horizontal bar 20 to the building H, in other words, it will be possible to fix the lower horizontal bar 20 to the building H after the vertical bar 30 is fixed to the lower horizontal bar 20.

The operation of the preferred embodiment of the invention is initiated with fixing one of the two horizontal bars, for example, the lower horizontal bar 20 to the side wall of the building H. The portion of the building H to which the lower horizontal bar 20 is fixed is a window sill constituting the lower part of the window frame. As shown in FlG. 1, the position of the horizontal bar 20 is preferably adjusted so that the upper edge of the vertical member 20b may extend substantially parallel to the top surface of the window sill. Thus, the horizontal bar 20 is fixed to the window sill by means of nails or setscrews 23 which will be passed through said holes 22.

In the next step shown in FIG. 2, two L-shaped vertical bars 30 will be fixed to the above horizontal bar 20. The vertical bars which will occupy the front central part of the finished window railing are preferably selected for the vertical bars concerned. The horizontal member 30b of the above-mentioned vertical bar 30 is placed onto the horizontal member 20a of the lower horizontal bar 20, and the rear surface of the horizontal member 30b is brought into close contact with the front surface of the vertical member 20b. Thus, these two vertical bars 30 and the lower horizontal bar 20 are fixedly connected to each other at right angles by means of the setscrews 24 which are inserted through the holes 32 and then threadedly engaged with the tapped holes 21.

In the third step illustrated in FIG. 3, the other horizontal bar, that is to say, the upper horizontal bar will be fixed to said two vertical bars 30 in the following manner. The vertical member 30a of the vertical bar is brought into contact with the front wall of the body member 100 of the upper horizontal bar at its rear surface, and then said horizontal bar 10 and two vertical bars 30 are interconnected at right angles by means of setscrews 33 which are passed through the holes 31 and threadedly engaged into the tapped holes 11. Since these L-shaped vertical bars 30 are of the same shape and dimention, and the tapped holes of the upper horizontal bar 10 are provided at the same spaces as the tapped holes 21 of the lower horizontal bar 20, said two vertical bars 30 can extend parallel to each other. For the same reason, the upper and lower horizontal bar 10 and 20 can be arranged in parallel to each other. In this way, the correct framework of the window railing can be surely constructed.

In the next step shown in FIG. 4, the upper horizontal bar 10 is fixed to the side of the building H by means of a setscrew 15. This setscrew passes through a hole in the rear leg 13 of the arm member 10b.

In the last step, the remainder of the L-shaped vertical bars 30 are fixed to both horizontal bar 10 and in the same manner as the above-mentioned. Alternatively, all of the nine vertical bars 30 may be fixed to them in the second step. Further, the vertical bar that will occupy each end portion of a finished window railing may be selected instead of said bars occupying the central portion in the second step. If the upper horizontal bar 10 can be surely held at right angles to the vertical bar 30 by another suitable arrangement, for example, by employing at least two setscrews, a single vertical bar 30 may be fixedly attached to one of the two horizontal bars at the second step.

In the other preferred embodiment of the present invention illustrated in FIG. 5, 6, 7 and 8, the window accessory is a window lattice which is composed of two horizontal bars 10 and 20 and nine vertical bars 30, and these components will be assembled by means of setscrews.

This upper horizontal bar 10 consists of a body member 10a of C-shaped cross section and a arm member 10b of U-shaped plate. The body member 10a is provided with a series of nine holes 11 which will serve as connections with the upper ends of the vertical bars 30. The front leg 12 of the arm member 10b is fixedly connected to the rear wall of the body member 10a by means of setscrews 14 and nut plate 16. The rear leg 13 of the arm member is adapted to be fixedly connected to the side wall of the building H by means of nails or setscrews 15. Since these connections 11 with the vertical bars 30 and connections 13 with the building H are provided in different portions in such a manner, fixing of the vertical bar 30 to the upper horizontal bar 10 will not interfere with fixing of the upper horizontal bar 10 to the building H, in other words, fixing of the upper horizontal bar 10 to the building H will not obstruct the vertical bar 30 to the upper horizontal bar 10. The lower horizontal bar 20 is constructed in the same manner as the upper horizontal bar 10, and the front leg 22 of the U-shaped arm member 20b is fixed to the rear wall of the C-shaped body member 20a by means of setscrews 24 and nut plate 26. The rear leg 23 of the arm member 20b is adapted to be fixedly connected to the building H by means of nails or setscrews 25. The vertical bar 30 is made of a square pipe. A tapped hole 31 that will serve as connection with the upper horizontal bar 10 is provided on the upper end portion of the rear wall of the vertical bar 30. On the other hand, a tapped hole 32 that will serve as connection with the lower horizontal bar 20 is firmed in the lower end portion of said rear wall.

The operation of the second embodiment of this invention is initiated with fixing one of the two horizontal bars,for example, the upper horizontal bar 10 to the side wall of the building H.

Firstly, the upper horizontal bar 10 is is fixedly connected to the side of the building H in the horizontal position. In this case, the upper window sill constituting the upper portion of the window frame may be utilized as a horizontal standard. The rear leg 13 of the arm member 10b will be fixed to the building by said setscrews after the body member 10a is positioned parallel to said window sill, as illustrated in FIG. 5a and 5b.

In the second step as shown in FIG. 6a and 6b, at least one vertical bar 30 which will occupy the front central portion of the finished window lattice is fixedly connected to said upper horizontal bar 10 at right angles by means of the setscrew 33 that will be passed through the hole 11 in the body member 10a and then threadedly engaged into the tapped hole 31 in the vertical bar 30. A ruler may be used to ensure such a right-angled arrangement, if desired.

In the third step of the present method, the other horizontal bar, that is to say, the lower horizontal bar 20 is fixedly connected to said vertical bar 30 at right angles by means of the setscrew 34 which will be passed through the hole 21 in the body member 20a and then threadedly engaged with the tapped hole 32 in the vertical bar 30. Thus, the lower horizontal bar 20 can extend parallel to the upper horizontalbar 10, because these holes 21 are provided at the same spaces as those holes 11. Consequently, the proper framework of this window lattice could be unerringly constructed, as illustrated in FIG. 7.

In the next step shown in FIG. 8a and 8b, said lower horizontal bar 20 is fixedly connected to the side wall of the building H. In this case, the rear leg 23 of the arm member 20b is fixed to the building H by nail or setscrew 25.

Lastly, the remainder of the invention bars 30 will be fixed to these horizontal bar and in the same manner as described before. Alternatively, all of those vertical bars 30 may be fixed to them at the second step. If the vertical bar that will stand at the end portion of the finished widow lattice will be selected for the vertical bar which is first fixed at the second step, the side surface of the window frame will be utilized for the s standard for arranging said vertical bar at right angles to the upper or lower horizontal bar 10 or 20.

According to the present invention, the window accessory can be fixedly attached to the side wall of the building H while being assembled at the same place, that is to say, at the height of the window. As a result of this, there is no need for storing the considerably heavy finished window accessory of great bulk in a warehouse and for transporting it to the remote attaching site. The window accessory need not be assembled at a shop, in other words, it can be stored and transported in the form of nonbulky components convenient for packing and handling. This contributes substantially to the mosy efficient utilization of storage space and considerable reduction of storing and transporting costs.

Furthermore, there is no need for lifting a bulky finished accessory of great weight up to the height of the window, because the window accessory need not be a assembled on the ground. This is the remarkable difference of the present invention from the simple knockdown window accessory of the prior art. Since such a window accessory may be transported and lifted up in the form of the comparatively light components of no great bulk, it can be completely assembled and attached by a single unskille'd worker. This reduction of required worker to a minimum will serve to reduce the assembling and attaching costs. Thus, this method according to the present invention will have numerous advantages if a considerable rise of personnel expenses is taken into consideration. In addition, there is no need for providing a scaffold or ladder, because all of the operations can be performed from the inside of the building H.

Furthermore, if setscrews are used as securing means of those components, any skilled worker is not required for assembling. Such a window accessory can be readily assembled by untrained hands. Of course, it is possible to use any other securing means than a setscrew, such as a anchor rivet in which a tapered pin will be hammered or drawn to open a skirt, or a key which will be inserted into a tongue of the vertical bar projecting into the opposite side of the horizontal bar. These securing means are preferably suitable for field operations Needless to say, it is possible to vary the material and shape of these horizontal or vertical bars. Other embodiments of the invention employing the same or equivalent principles may be used by those skilled in the art without departing from the present invention.
